Leviticus 23:37-39

Living Bible

³⁷ “(These, then, are the regular annual festivals—sacred convocations of all people—when offerings to the Lord are to be made by fire. ³⁸ These annual festivals are in addition to your regular Sabbaths—the weekly days of holy rest. The sacrifices made during the festivals are to be in addition to your regular giving and normal fulfillment of your vows.)

³⁹ “This last day of September, at the end of your harvesting, is the time to begin to celebrate this seven-day festival before the Lord. Remember that the first and last days of the festival are special days of rest.
